Just substitute every one of them in!

3*-5+4*1 is not bigger than 20

0^-5+-3*4 is not bigger than 20

3*-4+4*-2 is not bigger than 20

3*2+4*7=34 is bigger than 20

Therefore choosing answer D!

<u>Right Triangles</u>

In right triangles, where one of its internal angles measures 90°, the trigonometric ratios are satisfied.

We have completed the figure below with the missing internal angle A that measures A = 90° - 29° = 61° because the lines marked with an arrow are parallel.

Given the internal angle A, we can relate the unknown side of length x with the known side length of 500 ft, the hypotenuse of the triangle. We use the sine ratio:

$\displaystyle \sin 61^\circ=\frac{\text{opposite leg}}{\text{hypotenuse}}$

$\displaystyle \sin 61^\circ=\frac{x}{500}$

Solving for x:

$x = 500 \sin 61^\circ$

Calculating:

x = 437.3 ft

Suppose that the dollar cost of producing x appliances is c(x)=1000+ 90x- 0.2x 2

Aleksandr [31]

Answer:

Step-by-step explanation:

Given that the dollar cost of producing x appliances is

$c(x)=1000+ 90x- 0.2x^2$

A) Average cost can be obtained by dividing c(x) by units = x

i.e. average cost = $\frac{1000}{x} +90-0.2x$

B) Marginal cost = dC/dx = $90-0.4x$

When x=140 marginal cost $= 90-0.4(140)\\=34$

C) We calculate

c(140) = $=1000+90(140)-0.2(140^2)\\\\=9680$

c(141) = $=1000+90(141)-0.2(141^2)\\\\\\=9713.80$

Marginal cost = difference = 33.80

Same as 34 shown in marginal cost.

A survey found that 50% of teenagers prefer to watch a movie at a theater over other viewing options. You want to know the estim

ella [17]

Answer:

1. Flip a fair coin four times, with heads representing teenagers who prefer watching a movie at a theater and tails representing those who do not.

2. Pick a card from a deck of standard playing cards four times, with red suits representing those who prefer watching a movie at a theater and black suits representing those who do not.

4. Roll a six-sided die four times, with even numbers representing those who prefer watching a movie at a theater and odd numbers representing those who do not.

Step-by-step explanation:

Basically you need to do something 4 times, with each time having a 50/50 chance.

For 1, it flips the coin 4 times and a coin toss is 50/50

For 2, it pics 4 cards, and the deck of cards has a 50-50 chance of either red or black

For 3, it spins it only 3 times, so is wrong

For 4, it rolls the die 4 times, and even and odd is 50-50

For 5, 0-5 consist of 6 number, while 6-9 is only 4 numbers thus is not 50-50 so is wrong

slamgirl [31]

Answer:

n + p = m

Step-by-step explanation:

x(the unnamed angle) and m both equal 180

x + m = 180

x + n + p =180

180 = 180

x + m = x + n + p

m = n + p
